Right see your issue now which hasn’t been 100% clear from the various threads you’ve started.

what you want is either…

show items for collection near you (which is possible)

or

show items that are postage only. So you want to in that instance filter out items that only offer collection.

in any event you’d need two searches (one postage only, one local collection as most site searches don’t operate or rules like that) but yes a Postage only filter would probably be a useful addition. Unfortunately you are on a hope and a prayer that eBay add that to their roadmap as they don’t take recommendations from users via the forums.

best bet is to find the feedback button on a search page and state your requirements (which id limit to Postage only filter)
